Every single 2GR and I think every single 1GR as well for the VVT oil feeds

 

This V6 twin turbo Tundra has been waiting on a new engine for 6-7 months according to what the tech told me today. The main bearing lost oil pressure. He stated there’s 2 more Tundras parked in the back of the shop with the same issue. Convinced me to pass on the new power plant, at least for now.








I’ve put my Tundra thru its paces over the years with very minimal maintenance. I haven’t changed the spark plugs since 99k miles. Never changed the transmission fluid. Never added power steering fluid. Never changed brake fluid. It just runs man. The 2nd to last pic, I hauled over 3,300lbs of flower bed pavers 16 miles home. I didn’t go over 45-50mph. My face 😬😳 when the Home Depot guy lowered it in the bed. I had to go back for a 2nd load. I didn’t anticipate it being that heavy and since I was already there decided not to go home and grab a trailer.

I’ve kicked around the idea of getting my wife a LX 600 or the the new TX (only prefer the 550 PHEV) but with the uncertainty long term reliability of the new turbo power plants, we plan on hanging on to the LX 570. I would absolutely buy another 570. Recently for the first time I towed with the LX and it towed pretty darn good under 85mph. The 3100lbs car on trailer started to get squirrelly around 85+mph.

There’s 3 Tundras I’m aware of with over 1 million miles on them. The first guy received a brand new Tundra from Toyota. I’m sold on that reliability.

 

The EB engines like to blow turbos, consume oil from turbos, have severe carbon buildup pre-twin injection update around 2020, have water buildup in the intercoolers that can freeze in winter and split the coolers, oh and random rod failure. Chains also wear out around 120k and the cam phasers very commonly develop noise and low rpm miss-fire issues.

They are great engines, I've made a huge amount of money off them. Meanwhile I've never seen a single Toyota 5.7 to date

 

Solid engine Hopefully the new 3.4 will hold up

‘Nice pics. Looks great. The million mile tundra where Toyota have a new Tundra was the 4.7 V8

‘What models still use water cooled alternators?

 

Almost all of the highly equipped German cars use them, the newest ones are 48v instead and are the ones having controller issues currently

 

Think of how long it would last if you maintained it properly. I just am not wired that way, I enjoy maintaining my cars the way they are supposed to be maintained, so to me a requirement to do the maintenance vs being able to let is slide doesn't mean anything to me.

With that said though, Toyota has plenty of stories of NA engines that were very particular to maintenance schedules being followed. 3.0L V6s that sludged if owners extended oil changes, the thought is that the UR V8 in the LS460 develops oil use as it ages if you don't change oil MORE frequently than Toyota recommends...they're not immune to that at all.

If all you want is engine reliability thats a legitimate choice, I personally am just not happy with a vehicle that is that behind in design and tech, and I'm never going to keep a vehicle past 100k miles and I'm never going to skip scheduled maintenance, so I'm really not worried about turbo engines.

 

This one is a 5.7 V8 with 1 million miles on it. I saw it on YouTube.

 

You also have a hot-V engine, maintenance issues are just not a thing with those since all of the possible problem areas are now up top and don't require engine out/extreme annoyance to access. It's totally different with those types of engines and the only reason I have a turbo engine is because the hot-V is just so much easier to work on.

I pulled turbos off mine in 4 hours in my garage with nothing special needed, replacing/working on turbos on a low mounted car requires a lift if you want it done in any semblance of a fast timeframe or ease. Piping is much longer, more points of leaks, worse heat saturation of the suspension and engine mounts etc etc....

That's why I was stunned the new Toyota engine was not a hot-V and low mounted instead, they had every chance to do it right and yet still chose the configuration that makes servicing and packaging an pain.

 

People think that Toyota is good at that type of design and packaging and they aren't...

 

Another million mile Toyota engine is the 22R in-line 4. I still see trucks with that engine running around. The trucks are usually beat to hell and it’s somewhat amazing they are still on the road.

 

Yeah, it's still shocking since they had 10 years to copy/refine off others who did it first.

I've been noticing that Toyota almost assumes since nothing will break that packaging for ease of work isn't considered. Not really a bad thing/a problem at all but working on a Chrysler 3.6 van and then a 3.5 Toyota back to back it's very interesting. The 3.6 needed lifters (systemic issue for that engine long term, zero concern for you) and it was quite easy to get to what I needed. The 3.5 only needed valve covers/plugs but it took nearly the same amount of time

 

Who claims this? What kind of examples do you have?

 

I think that’s likely true…

This issue with the turbos. Starters in the UZ and UR V8s, O2 sensor locations on the UR V8 with AWD…just to name a couple. They have a knack for designing an engine layout that creates layers of complexity for making simple repairs.

 

the UZ starter location i think almost ties back to the 48V / ISG talks from earlier... yes putting the starter between the cylinder banks makes it more annoying to reach, but also means it's more protected from external substances that could corrode/jam it more quickly

 

Yet a starter repair is really common on that car…
